Nikovoke Aquarium Air Stone Disc, Fish Tank Bubble Diffuser with 4mm Hose Connector for Air Pump - 10cm 13cm for Small Ponds

• 【High-efficiency Oxygenation】It generates uniform and fine bubbles, effectively increasing the oxygen content in the fish tank water, creating a healthy living environment for fish and aquatic organisms.
• 【Uniform Air Pressure】It is made by high-purity corundum through high-temperature sintering and has an internal air pressure balance chamber to ensure uniform air release, with a higher oxygenation efficiency than traditional bubble stones.
• 【Aquatic Ecology】When you notice that the ornamental fish frequently surface or the water quality tends to become turbid, placing the air disc at the bottom of the tank will form a fog-like bubble curtain.
• 【Source of Vitality】The 10cm and 13cm sizes are suitable for small and medium-sized aquariums. It runs quietly without affecting the viewing experience. It is recommended to purchase the corresponding size based on the size of the fish tank.
• 【Oxygen Dance】When the fish swim vigorously in the oxygen-rich water, this seemingly simple round disc is the behind-the-scenes hero that keeps the water clear forever.
